Corneal laceration by sharp objects in children seven years of age and younger

PURPOSE: Young children are prone to develop amblyopia after penetrating injury. We sought to evaluate the management of penetrating corneal injury without intraocular foreign body (IOFB) in children ≤7 years old and to assess the long-term visual acuity results. METHODS: A retrospective chart review was performed in 2 ophthalmology departments to identify children ≤7 years old with penetrating corneal injury from sharp objects that had follow-up of >18 months. Data retrieved included all details from the initial examination, surgical procedures, amblyopia prevention measures, and final visual acuity. RESULTS: Twenty children eligible for the study were identified. The mean age was 4.3 years, and mean follow-up time was 58 months. The corneal wound size range was 1-10 mm, with 8 eyes having wounds ≥6 mm. All patients required primary surgical management. Traumatic cataract extraction was performed at the primary operation in 6 eyes, with intraocular lens (IOL) implantation in 4 eyes. Additional surgical procedures were performed in 12 eyes. Yttrium-Aluminum-Garnet (YAG) capsulotomy was performed in 3 eyes with secondary cataract. Twelve patients required spectacle or contact lens correction, and 11 patients had patching for amblyopia prevention. At the end of follow-up, visual acuity was 20/40 or better in 14 eyes, 20/50 to 20/100 in 4 eyes, no light perception (NLP) in 1 eye, and unknown in 1 eye. CONCLUSIONS: Proper management of penetrating corneal injury in young children can result in excellent visual rehabilitation. Major measures include prompt traumatic cataract extraction with either primary or secondary IOL implantation, opening of posterior capsular opacification with YAG laser, correction of refractive errors, and patching for amblyopia prevention.
